DETAILED DESCRIPTION

Before turning to the figures, which illustrate certain exemplary embodiments in detail, it should be understood that the present disclosure is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology used herein is for the purpose of description only and should not be regarded as limiting.

According to an exemplary embodiment, a battery pod assembly for a refuse vehicle is disclosed herein. The battery pod assembly of the present disclosure provides many advantages over conventional systems. The battery pod assembly may include various stress mitigation devices to mitigate mechanical stress (e.g., tensile stress, compressive stress, shear stress, cyclic stress, etc.), thermal stress (e.g., thermal cycling, thermal events, etc.), and/or physical ingress (e.g., water ingress, debris ingress, chemical ingress, etc.) on the battery pod assembly and components thereof.

According to various exemplary embodiments, the battery pod assembly may be positioned in various locations on the refuse vehicle such that the battery pod assembly is readily accessible for regular maintenance. Additionally, components of the battery pod assembly may be modular such that the components can be swapped out or upgraded. For example, a battery cell may be upgraded to future battery cell chemistries not yet available.

According to various exemplary embodiments, the refuse vehicle includes batteries positioned in a longitudinal direction between chassis frame rails of the refuse vehicle, between body frame rails of the refuse vehicle, or between both the chassis frame rails of the refuse vehicle and the body frame rails of the refuse vehicle. The batteries can be the battery pod assembly and may include housings. The batteries may be stacked in a lateral or vertical direction and positioned between the chassis frame rails, between the body frame rails, or between both the chassis and the body frame rails. The chassis frame rails and the body frame rails define a space within which the batteries can be positioned. The batteries can be fastened or coupled with the body frame rails and/or the chassis frame rails depending on configuration and positioning. The batteries can be hung from an underside of the body of the refuse vehicle.

As shown in FIG. 1 , a vehicle, shown as refuse vehicle 10 (e.g., a garbage truck, a waste collection truck, a sanitation truck, a recycling truck, etc.), is configured as a front-loading refuse truck. In other embodiments, the refuse vehicle 10 is configured as a side-loading refuse truck or a rear-loading refuse truck. In still other embodiments, the vehicle is another type of vehicle (e.g., a skid-loader, a telehandler, a plow truck, a boom lift, etc.). As shown in FIG. 1 , the refuse vehicle 10 includes a chassis, shown as frame 12; a body assembly, shown as body 14, coupled to the frame 12 (e.g., at a rear end thereof, etc.); and a cab, shown as cab 16, coupled to the frame 12 (e.g., at a front end thereof, etc.) forward of the body 14. The cab 16 may include various components to facilitate operation of the refuse vehicle 10 by an operator (e.g., a seat, a steering wheel, actuator controls, a user interface, switches, buttons, dials, etc.).

As shown in FIG. 1 , the refuse vehicle 10 includes a prime mover, shown as electric motor 18, and an energy system, shown as a battery pod assembly 20. In other embodiments, the prime mover is or includes an internal combustion engine (e.g., a hybrid engine, etc.). According to the exemplary embodiment shown in FIG. 1 , the electric motor 18 is coupled to the frame 12 at a position beneath the cab 16. The electric motor 18 is configured to provide power to a plurality of tractive elements, shown as wheels 22 (e.g., via a drive shaft, axles, etc.). In other embodiments, the electric motor 18 is otherwise positioned and/or the refuse vehicle 10 includes a plurality of electric motors to facilitate independently driving one or more of the wheels 22. In still other embodiments, the electric motor 18 or a secondary electric motor is coupled to and configured to drive a hydraulic system that powers hydraulic actuators. According to the exemplary embodiment shown in FIG. 1 , the battery pod assembly 20 is coupled to the frame 12 beneath the body 14. In other embodiments, the battery pod assembly 20 is otherwise positioned (e.g., within a tailgate of the refuse vehicle 10, beneath the cab 16, along the top of the body 14, within the body 14, etc.).

According to an exemplary embodiment, the battery pod assembly 20 is configured to receive, generate, and/or store power. The battery pod assembly 20 is also configured to provide electric power to the electric motor 18 to drive the wheels 22, electric actuators of the refuse vehicle 10 to facilitate operation thereof (e.g., lift actuators, tailgate actuators, packer actuators, grabber actuators, etc.), and/or other electrically operated accessories of the refuse vehicle 10 (e.g., displays, lights, user controls, etc.). The battery pod assembly 20 may include one or more rechargeable batteries (e.g., lithium-ion batteries, nickel-metal hydride batteries, lithium-ion polymer batteries, lead-acid batteries, nickel-cadmium batteries, iron-ion batteries, etc.), capacitors, solar cells, generators, power buses, etc. In one embodiment, the refuse vehicle 10 is a completely electric refuse vehicle. In other embodiments, the refuse vehicle 10 includes an internal combustion generator that utilizes one or more fuels (e.g., gasoline, diesel, propane, natural gas, hydrogen, etc.) to generate electricity. The electricity may be used to charge one or more batteries of the battery pod 20, power the electric motor 18, power the electric actuators, and/or power the other electrically operated accessories (e.g., a hybrid refuse vehicle, etc.). For example, the refuse vehicle 10 may have an internal combustion engine augmented by the electric motor 18 to cooperatively provide power to the wheels 22. The battery pod assembly 20 may thereby be charged via an on-board generator (e.g., an internal combustion generator, a solar panel system, etc.), from an external power source (e.g., overhead power lines, mains power source through a charging input, etc.), and/or via a power regenerative braking system. In these arrangements, the battery pod assembly 20 may include a power interface structure to facilitate charging the batteries of the battery pod assembly. The power interface may be configured to receive power from the on-board generator or the external power source. The battery pod assembly 20 may then provide power to the electrically operated systems of the refuse vehicle 10. In some embodiments, the battery pod assembly 20 provides the power to the to the electrically operated systems of the refuse vehicle 10 via the power interface. In some embodiments, the battery pod assembly 20 includes a heat management system (e.g., liquid cooling, heat exchanger, air cooling, etc.).

According to an exemplary embodiment, the refuse vehicle 10 is configured to transport refuse from various waste receptacles within a municipality to a storage and/or processing facility (e.g., a landfill, an incineration facility, a recycling facility, etc.). As shown in FIG. 1 , the body 14 includes a plurality of panels, shown as panels 32, a tailgate 34, and a cover 36. The panels 32, the tailgate 34, and the cover 36 define a collection chamber (e.g., hopper, etc.), shown as refuse compartment 30. Loose refuse may be placed into the refuse compartment 30 where it may thereafter be compacted (e.g., by a packer system, etc.). The refuse compartment 30 may provide temporary storage for refuse during transport to a waste disposal site and/or a recycling facility. In some embodiments, at least a portion of the body 14 and the refuse compartment 30 extend above or in front of the cab 16. According to the embodiment shown in FIG. 1 , the body 14 and the refuse compartment 30 are positioned behind the cab 16. In some embodiments, the refuse compartment 30 includes a hopper volume and a storage volume. Refuse may be initially loaded into the hopper volume and thereafter compacted into the storage volume. According to an exemplary embodiment, the hopper volume is positioned between the storage volume and the cab 16 (e.g., refuse is loaded into a position of the refuse compartment 30 behind the cab 16 and stored in a position further toward the rear of the refuse compartment 30, a front-loading refuse vehicle, a side-loading refuse vehicle, etc.). In other embodiments, the storage volume is positioned between the hopper volume and the cab 16 (e.g., a rear-loading refuse vehicle, etc.).

As shown in FIG. 1 , the refuse vehicle 10 includes a lift mechanism/system (e.g., a front-loading lift assembly, etc.), shown as lift assembly 40, coupled to the front end of the body 14. In other embodiments, the lift assembly 40 extends rearward of the body 14 (e.g., a rear-loading refuse vehicle, etc.). In still other embodiments, the lift assembly 40 extends from a side of the body 14 (e.g., a side-loading refuse vehicle, etc.). As shown in FIG. 1 , the lift assembly 40 is configured to engage a container (e.g., a residential trash receptacle, a commercial trash receptacle, a container having a robotic grabber arm, etc.), shown as refuse container 60. The lift assembly 40 may include various actuators (e.g., electric actuators, hydraulic actuators, pneumatic actuators, etc.) to facilitate engaging the refuse container 60, lifting the refuse container 60, and tipping refuse out of the refuse container 60 into the hopper volume of the refuse compartment 30 through an opening in the cover 36 or through the tailgate 34. The lift assembly 40 may thereafter return the empty refuse container 60 to the ground. According to an exemplary embodiment, a door, shown as top door 38, is movably coupled along the cover 36 to seal the opening thereby preventing refuse from escaping the refuse compartment 30 (e.g., due to wind, bumps in the road, etc.).

As shown in FIG. 2 , the battery pod assembly 20 is coupled to a portion 11 of the refuse vehicle 10. The battery pod assembly 20 includes a shell show as pod structure 60 and one or more energy storage devices shown as batteries 80. The pod structure 60 defines an internal volume 62 of the battery pod assembly 20. The pod structure 60 includes an portal shown as door 61. The door 61 allows a user to access the internal volume 62 from outside of the pod structure 60. The pod structure 60 is configured to mitigate the transmission of mechanical loads (e.g., vibrations, shock, stress, etc.) from outside the battery pod assembly 20 to the internal volume 62. Additionally, the pod structure 60 is configured to mitigate water, debris, or chemicals from entering the internal volume 62. In some embodiments, the pod structure 60 includes a thermal insulating layer configured to mitigate against thermal stress such as thermal cycling or thermal events. In other embodiments the pod structure 60 may also electrically couple the batteries 80 to each other and/or to the electrical systems of the refuse vehicle 10.

The battery pod assembly 20 includes one or more vehicle coupling devices shown as external dampers 65 (e.g., dampers and/or isolators). The external dampers 65 are disposed between the pod structure 60 and the refuse vehicle 10 and are configured to couple the battery pod assembly 20 to the portion 11 of the refuse vehicle 10. The dampers 65 are also configured to mitigate the transmission of active and/or passive mechanical loads from the refuse vehicle to the battery pod assembly 20 (e.g., to the pod structure 60). That is, the external dampers 65 are configured as mechanical dampers such as a mechanical dashpot, a fluid/hydraulic dashpot, a shock absorber, etc. In other embodiments, the battery pod assembly may include other coupling devices (e.g., pins, linkages, latches, etc.) to couple the pod structure 60 to the refuse vehicle 10.

The battery pod assembly 20 also includes one or more battery coupling devices shown as internal dampers 68 (e.g., dampers and/or isolators). The internal dampers 68 are disposed within the internal volume 62 and between the pod structure 60 and one or more of the batteries 80. The internal dampers 68 are configured to couple the batteries 80 to the pod structure 60. The internal dampers 68 are also configured to mitigate the transmission of active and/or passive mechanical loads from the pod structure 60 to the batteries 80. In some embodiments, the internal dampers 68 may be the same or substantially similar in structure to the external dampers 65. In other embodiments, the internal dampers 68 are configured as a different type of mechanical damper. For example, the external dampers 65 may be configured as fluid/hydraulic dashpots and the internal dampers 68 may be configured as mechanical dashpots.

In some embodiments, the external dampers 65 and/or the internal dampers 68 are also configured to capture energy from the active and/or passive mechanical loads. For example, the external dampers 65 and/or the internal dampers 68 may utilize piezoelectric systems or other suitable systems to capture active and/or passive vibrations passing through the external dampers 65 and/or the internal dampers 68.

The battery pod assembly 20 also includes a thermal management system 70. The thermal management system is configured to mitigate against thermal stress such as thermal cycling or thermal events. The source of the thermal stress may come from within the battery pod assembly 20 (e.g., typical thermal energy generation from a conventional battery) or from an external source (e.g., a thermal event near the refuse vehicle 10). In some embodiments, the thermal management system is configured to actively control the temperature of the battery pod assembly 20 within a specified range. Accordingly, the thermal management system 70 may advantageously improve the operation of the refuse vehicle, for example, by keeping the batteries 80 within ideal operating temperatures thus increasing the lifespan of the batteries 80.

The thermal management system includes various sensing devices shown as external sensors 71 and internal sensors 72. The external sensors 71 are positioned on or near the pod structure 60 and are configured to sense an external temperature of the battery pod assembly 20. The internal sensors 72 are positioned within the internal volume 62 and are configured to sense an internal temperature of the battery pod assembly 20.

According to various exemplary embodiments, the thermal management system 70 may include a cooling assembly configured to reduce the temperature of the battery pod assembly 20 and/or components thereof (e.g., the batteries 80). In some embodiments, the cooling assembly may utilize a liquid cooling system that includes a thermal transfer liquid, a cold plate, a pump, a radiator, and radiator fans. In other embodiments, the cooling assembly may utilize an air cooling system that includes a heatsink and fans. In still other embodiments, the cooling assembly may utilize other cooling systems including thermoelectric devices (e.g., Peltier), heat pumps, fans, radiators, etc.

In other exemplary embodiments, the thermal management 70 system includes a heating assembly configured to increase the temperature of the battery pod assembly 20 and/or components thereof (e.g., the batteries 80). The heating assembly may utilize an electric heating device or other heating systems such as a thermoelectric device (e.g., Peltier), heat pumps, etc.

In some embodiments, the thermal management system 70 includes a controller. In some embodiments, the controller 70 is part of a temperature control system of the refuse vehicle 10 (e.g., a chassis temperature controller). In other embodiments, the controller 70 is a separate device coupled to the refuse vehicle 10. The controller may be coupled to one or more of the external sensors 71, the internal sensors 72, the cooling assembly, and the heating assembly. The controller may be configured to receive temperature data from one or more of the external sensors 71 and the internal sensors 72. The controller may also be configured to operate one or more of the cooling assembly and the heating assembly based on the temperature data. For example, one or more of the external sensors 71 and the internal sensors 72 may provide temperature data indicating that the battery pod assembly 20 is below ideal operating temperatures. The controller may operate the heating assembly to increase the operating temperature of the battery pod assembly 20.

Still referring to FIG. 2 , the batteries 80 are configured to store and provide electrical energy. The batteries 80 may each have a single battery cell or multiple battery cells (e.g., a battery pack). Additionally, the batteries 80 may be configured to have a particular electrochemistry (e.g., lithium-ion, nickel-metal hydride, lithium-ion polymer, lead-acid, nickel-cadmium, iron-ion, etc.).

In some embodiments, the batteries 80 may be removably coupled to the battery pod assembly 20 (e.g., coupled to the pod structure 60 via the internal dampers 68) such that the batteries 80 are replaceable and/or upgradable. For example, a user may access the internal volume 62 to add, remove, replace and/or upgrade the batteries 80. In still other embodiments, the battery pod assembly 20 may be removably coupled to the refuse vehicle 10 such that a battery pod assembly 20 may be added, removed, replaced, and/or upgraded.

The battery pod assembly 20 may include an electric connection (e.g., a pantograph, a current collector, a high-voltage line, etc.) shown as power interface 81 to allow the battery pod assembly 20 to connect to external power sources (e.g., an overhead power line, the grid, a charging station, etc.). For example, the battery pod assembly 20 may include a charging port to allow the batteries 80 to be charged while the battery pod assembly 20 is coupled to the refuse vehicle 10 (e.g., by a 220V charger). In some embodiments, the battery pod assembly 20 includes an electrical bypass to power the refuse vehicle 10 from a charging source while the battery is being charged. In some embodiments, the battery pod assembly 20 connects to one or more power sources of refuse vehicle 10 (e.g., an internal combustion generator, a battery, etc.) to charge the batteries 80 of the battery pod assembly 20. For example, the battery pod assembly 20 may include a connection to an onboard diesel generator configured to provide power to the battery pod assembly 20 for charging the batteries 80. In these arraignments, the battery pod assembly 20 may connect to internal or external power supplies or components via the power interface 81.

The battery pod assembly 20 may be modular such that the components of the battery pod assembly 20 may be easily removed, replaced, added, or upgraded. Additionally, the battery pod assembly 20 may be modular with itself such that two or more battery pods 20 may be coupled. For example, a particular refuse vehicle may require less power storage and therefore may include fewer batteries 80 within the batter pod assembly 20. Conversely, a refuse vehicle may require more power and include more batteries 80 and/or more battery pod assemblies 20. In these arrangements, the thermal management system may also be modular. For example, the thermal management system 70 may include a separate thermal management assembly (e.g., a heating assembly, a cooling assembly, etc.) for each of the batteries 80. Alternatively, the thermal management system 70 may include modular thermal transfer devices (e.g., a cold plate, etc.) for each of the batteries 80. For example, the cooling assembly may be configured as a water cooling assembly having one or more cold plates for each of the batteries 80 and quick disconnect tubing to easily add or remove batteries. Alternatively, the thermal management system 70 may include a modular rack system configured to receive the batteries 80. The modular rack system may be configured to provide heating and/or cooling to the batteries 80.

Now referring generally to FIGS. 3-10 , the battery pod assembly 20 may be positioned in various locations on the refuse vehicle 10. For example, the battery pod may be coupled to the frame 12, the body 14, the cab 16, or other parts of the refuse vehicle 10. In other embodiments, the refuse vehicle 10 may include more than one battery pod assembly 20. In these arrangements, each of the battery pod assemblies 20 may similarly be coupled to the frame 12, the body 14, the cab 16, or other parts of the refuse vehicle 10. The geometry of the pod structure 60 may change to suitably conform to the location of the battery pod assembly 20.

As shown in FIG. 3 , the battery pod assembly 20 is coupled to the rearward top portion of the body 14. In other embodiments, the battery pod assembly 20 is coupled to the forward top portion of the body 14. In some embodiments, the battery pod assembly 20 is removable/detachable from the body 14. Locating the battery pod assembly 20 on top of the body 14 allows easy access to the battery pod assembly 20. For example, a user may readily inspect and service the battery pod assembly 20 because it is located on an external surface of the refuse vehicle 10.

As shown in FIG. 4 , the battery pod assembly 20 is coupled to the rearward bottom portion of the body 14. In other embodiments, the battery pod assembly 20 is coupled to the forward bottom portion of the body 14. As described above, battery pod assembly 20 may be removable/replaceable. For example, the refuse vehicle 10 may include a door on the side of the body 14 to allow removal and replacement of the battery pod assembly 20. In some embodiments, the battery pod assembly 20 is located on a track such that the battery pod assembly 20 can be slid out from the body 14 similar to a drawer.

As shown in FIG. 5 , the battery pod assembly 20 is coupled between the cab 16 and the body 14. In some embodiments, the battery pod assembly 20 is coupled to the frame 12. Locating the battery pod assembly 20 between the cab 16 and the body 14 reduces a rear weight of the refuse vehicle 10, thereby reducing component stress of weight bearing members (e.g., a rear axle). Furthermore, centrally locating the battery pod assembly 20 protects the battery pod assembly 20 from damage in a mechanical impact event. Furthermore, centrally locating the battery pod assembly 20 allows easy modification/retrofitting of existing refuse vehicles to include the battery pod assembly 20. The battery pod assembly 20 may be easily accessed and/or removed from the refuse vehicle 10. For example, the battery pod assembly 20 may include forklift pockets so that a forklift may easily remove the battery pod assembly 20 from the refuse vehicle 10. In some embodiments, the battery pod assembly 20 includes one or more eyelet connectors to receive a lifting hook or similar hoisting attachment. The battery pod assembly 20 may be configured to connect to an external rail system to quickly replace the battery pod assembly 20 by sliding it orthogonally off the refuse vehicle 10.

In some embodiments, the battery pod assembly 20 is configured to dynamically change position on the refuse vehicle 10 based on loading of the refuse vehicle 10. For example, the battery pod assembly 20 may translate horizontally along the frame 12 toward the cab 16 or toward the body 14 to change a weight distribution of the vehicle. In some embodiments, the battery pod assembly 20 includes one or more controllers to measure the weight distribution of the refuse vehicle 10 and adjust a position of the battery pod assembly 20 accordingly.

As shown in FIG. 6 , the battery pod assembly 20 is coupled to the tailgate 34 of the refuse vehicle 10. In some embodiments, the battery pod assembly 20 is positioned vertically along a rearward side of the refuse compartment 30. In some embodiments, the battery pod assembly 20 is positioned substantially near the base of the tailgate 34 or as part of the tailgate 34. The battery pod assembly 20 may be configured to be accessible via the tailgate 34. For example, a user could open the tailgate 34 to reveal battery pod assembly 20. In some embodiments, the tailgate 34 includes one or more rotating elements (e.g., hinges, mechanical bearings) to facilitate rotation around a rearward corner of the refuse compartment 30. For example, the tailgate 34 could include one or more hinging mechanisms on a side to allow a user to open the tailgate 34 like a door and gain access to the battery pod assembly 20 located along the frame 12 of the refuse vehicle 10. In some embodiments, the tailgate 34 is a double door. Swinging the tailgate 34 open like a door requires less energy than lifting the tailgate 34.

In some embodiments, the tailgate 34 is fully integrated with the battery pod assembly 20 and is configured to be removable/replaceable. For example, a first tailgate 34 having a first battery pod assembly 20 could be replaced by a second tailgate 34 having a second battery pod assembly 20 when the batteries 80 of the first battery pod assembly 20 are depleted of energy. Removing and replacing the tailgate 34 may limit loss of vehicle operation due to charging time because the tailgate 34 including the depleted battery pod assembly 20 may be charged separately of the refuse vehicle 10. Furthermore, swappable battery pod assemblies enable a smaller fleet of refuse vehicles to service the same area because the reduced downtime associated with battery charging enables the refuse vehicles to operate for longer periods of time. In some embodiments, a number of racks index one or more battery cells of the battery pod assembly 20.

As shown in FIG. 7 , the battery pod assembly 20 is coupled between the body 14 and the frame 12 (e.g., on a sub-frame). As described above, in some embodiments, the battery pod assembly 20 may be configured to translate horizontally along the frame 12 of the refuse vehicle 10. For example, the battery pod assembly 20 could move between a forward portion and a rearward portion of the body 14 of the refuse vehicle 10 such that the refuse vehicle 10 is evenly loaded. As described above, in some embodiments, the battery pod assembly 20 is removable and/or replaceable. The battery pod assembly 20 may be accessed via a door on a side of the body 14 or via the tailgate 34. Similarly, the battery pod assembly 20 may be removed and/or replaced by another battery pod assembly. Alternatively, one or more individual battery cells (e.g., batteries 80 of FIG. 2 ) of the battery pod assembly 20 could be replaced. In some embodiments, the battery pod assembly 20 can be accessed by removing the refuse compartment 30. For example, a refuse vehicle with a removable refuse compartment (e.g., a container truck) may remove the refuse compartment to reveal the battery pod assembly 20. In some embodiments, the battery pod assembly 20 is coupled to the refuse compartment 30 itself and can be removed with the refuse compartment 30. For example, a refuse vehicle could swap a first full refuse compartment with a first battery pod assembly having depleted batteries for a second empty refuse compartment with a second battery pod assembly having charged batteries.

Referring now to FIGS. 8A-9B, several illustrations of an exemplary placement of the battery pod assembly 20 are shown, according to several exemplary embodiments. In various embodiments, the battery pod assembly 20 is coupled to a rearward top portion of the refuse vehicle 10 (e.g., above the refuse compartment 30, etc.). Additionally or alternatively, the battery pod assembly 20 is coupled to a rearward portion of the refuse vehicle 10. For example, the battery pod assembly 20 may be coupled to the tailgate 34 and/or a rearward portion of the refuse compartment 30 (e.g., as shown in FIGS. 8A-8C). As another example, the battery pod assembly 20 may be coupled to a vertical rear surface of the refuse compartment 30. In some embodiments, the battery pod assembly 20 or components thereof are coupled to the wheel 22. In some embodiments, the battery pod assembly 20 is coupled to a front and rear wheelset of the refuse vehicle 10 (e.g., as shown in FIGS. 8A-8C). In various embodiments, placement of the battery pod assembly 20 as shown in FIGS. 8A-8C facilitates shifting weight rearward on the refuse vehicle 10, thereby reducing strain on forward load bearing components (e.g., a front axle, etc.). In some embodiments, the placement of the battery pod assembly 20 shown in FIGS. 8A-8C is preferred for a rear-loading refuse vehicle 10. In various embodiments, the battery pod assembly 20 includes a different number and/or arrangement of components than shown explicitly in the FIGURES. For example, the battery pod assembly 20 may include a first component coupled to an exterior hub surface of the front wheels 22 electrically coupled to a second component integrated with the tailgate 34. In some embodiments, the placement of the battery pod assembly 20 shown in FIGS. 9A-9B is preferred for a front-loading refuse vehicle 10 and/or a side-loading refuse vehicle 10. For example, the battery pod assembly 20 may be positioned on the lift assembly 40. In various embodiments, the battery pod assembly 20, or components thereof, are detachable from the refuse vehicle 10 as described in detail above.

Referring now to FIGS. 10A-10B, several illustrations of another exemplary placement of the battery pod assembly 20 are shown, according to several exemplary embodiments. In various embodiments, the battery pod assembly 20 is coupled to a top portion of the refuse vehicle 10. For example, the battery pod assembly 20 may be coupled to a top portion of refuse compartment 30 and/or above the cab 16 (e.g., as shown in FIGS. 10A-10B). In some embodiments, the battery pod assembly 20 is coupled to a canopy (or other structural element) located above the cab 16. Additionally or alternatively, the battery pod assembly 20, or components thereof, may be coupled to the wheels 22. For example, a first component of the battery pod assembly 20 (e.g., a battery cell, etc.) may be coupled to an exterior hub region of the wheels 22 and a second component of the battery pod assembly 20 (e.g., a power converter, etc.) may be coupled to a structural element (e.g., a portion of frame 12, etc.) above the cab 16. In some embodiments, the placement of the battery pod assembly 20 shown in FIGS. 10A-10B is preferred for a rear-loading refuse vehicle 10. In various embodiments, the placement of the battery pod assembly 20 as shown in FIGS. 10A-10B facilitates moving weight (e.g., battery weight, etc.) forward on the refuse vehicle 10 (e.g., toward the cab 16 and away from the tailgate 34, etc.), thereby reducing stress on rear load-bearing components (e.g., a rear axle, etc.).

Referring now to FIGS. 11A-11B and 12A-12B, the refuse vehicle 10 includes one or more batteries 100 (e.g., electrical energy storage devices, battery cells, housings including battery cells, etc.) for providing electrical power or electrical energy to various electrical components of the refuse vehicle 10, according to an exemplary embodiment. For example, the batteries 100 can provide or discharge electrical energy to power one or more components, devices, lift assemblies, compaction apparatuses, chassis systems, body systems, accessories, lights, etc., of the refuse vehicle 10. The batteries 100 described herein may be the same as or similar to the battery pod assembly 20 described in greater detail above, according to one exemplary embodiment. In another exemplary embodiments, the batteries 100 described herein can be housings that are structurally coupled with the refuse vehicle 10 that include battery cells (e.g., batteries 80).

Referring particularly to FIGS. 11A-11D, the batteries 100 can be positioned between rails of the frame 12, according to an exemplary embodiment. The frame 12 can include a left frame member 15 and a right frame member 13 that are spaced apart in a lateral direction perpendicular to the longitudinal direction. The frame 12 extends in and/or defines a longitudinal direction of the refuse vehicle 10. The batteries 100 can be spaced apart along the left frame member 15 and the right frame member 13. Referring particularly to FIGS. 11C-11D, the right frame member 13 and the left frame member 15 can be C-shaped brackets (shown in FIG. 11C), L-shaped brackets (shown in FIG. 11D), or any other shaped brackets. The right frame member 13 and the left frame member 15 define a space, a volume, an area, a gap, etc., therebetween, shown as space 17. The space 17 may have a height that is substantially equal to a height (e.g., in a lateral direction) of the right frame member 13 and the left frame member 15. In some embodiments, the batteries 100 are positioned within the space 17 between the right frame member 13 and the left frame member 15. In some embodiments, the batteries 100 are positioned between the right frame member 13 and the left frame member 15 and are longitudinally spaced (as shown in at least FIGS. 11A-11B) along the frame 12. The batteries 100 can be equally spaced along the frame 12, or unevenly spaced.

Referring particularly to FIGS. 11C-11D, the batteries 100 can be coupled with the right frame member 13 and the left frame member 15 along a top, a bottom, or sides of the batteries 100. For example, the batteries 100 can be coupled with the right frame member 13 and the left frame member 15 through fasteners 26 and dampers 24. The dampers 24 can be positioned between an interior surface of the right or left frame members 13 or 15 and an exterior surface of the batteries 100 (or a housing thereof) to absorb vibrations that may occur when the refuse vehicle 10 operates (e.g., as the refuse vehicle 10 transports). The fasteners 26 may pass through an opening of the dampers 24 and extend a distance into the batteries 100 (e.g., a housing of the batteries 100) and at least partially into the right frame member 13 or the left frame member 15.

In some embodiments, a top portion, a top edge, an upper periphery, etc., of the frame 12 defines a first plane or a first boundary 28 (e.g., an upper periphery or boundary of the space 17), and a bottom portion, a bottom edge, a lower periphery, etc., of the frame 12 defines a second plane or a second boundary 48 (e.g., a lower periphery or boundary of the space 17). In some embodiments, the batteries 100 are positioned entirely within the space 17 between the first boundary 28 and the second boundary 48. In some embodiments, the batteries 100 are positioned above the second boundary 48 so that the batteries 100 do not protrude downwards beyond the second boundary 48.

In some embodiments, dampers 24 and fasteners 26 are used to couple the batteries 100 with a bottom portion 42 of the right frame member 13 and the left frame member 15 (e.g., if the frame members 13 and 15 include bottom flanges such as in the L-shaped and C-shaped configurations shown in FIGS. 11C-11D). In some embodiments, the batteries 100 rest on top of the bottom portions 42 of the right frame member 13 and the left frame member 15 (e.g., with or without the dampers 24 positioned therebetween). In some embodiments, the dampers 24 and fasteners 26 are arranged along a top or bottom surface to absorb longitudinal vibrations, and/or along sides of the batteries 100 to absorb transverse or lateral vibrations.

Referring particularly to FIGS. 12A-12C, the batteries 100 can be positioned between the frame 12 and the body 14 (e.g., in a floor of the body 14). In some embodiments, the body 14 and the frame 12 define a space 19 therebetween (e.g., between a floor surface 66 of the body 14 and a top surface or upper periphery of the frame 12). The batteries 100 can be positioned within the space 19 and spaced longitudinally along the frame 12 and the body 14 (e.g., as shown in FIG. 12C). In some embodiments, the batteries 100 are fastened to the body 14 and hang from an underside of the body 14. In some embodiments, the batteries 100 are coupled with the body 14 and/or the frame 12 similarly to as described in greater detail above with reference to FIGS. 11A-11D. In some embodiments, the batteries 100 hang from the underside of the body 14, or are positioned within a floor of the body 14. The batteries 100 can extend downwards and terminate at an upper surface of the frame 12, terminate above the upper surface of the frame 12, or extend into the space 17 between the frame members 13 and 15. In some embodiments, the batteries 100 are also coupled with the frame 12.

The batteries 100 can be positioned at least partially within the space 19 defined by the body 14 and the frame 12. In some embodiments, the batteries 100 extend upwards into a space 64 within the body 14 so that the batteries 100 are at least partially positioned within the space 64. For example, the batteries 100 can be positioned at a floor surface 66 of the body 14 and may extend at least partially downwards into the space 19 between the body 14 and the frame 12 (e.g., terminating within the space 19, terminating at a boundary of the space 19, etc.).

Referring particularly to FIG. 13A, the body 14 may include a right frame member 82 and a left frame member 84 (e.g., a right body frame member and a left body frame member), according to an exemplary embodiment. The right frame member 82 and the left frame member 84 of the body 14 extend in a same direction as the frame 12. Specifically, the right frame member 82 and the left frame member 84 extend in the longitudinal direction along at least a portion of an entire longitudinal length of the body 14. The right frame member 82 and the left frame member 84 can be spaced apart a lateral distance that is equal to, greater than, or less than the lateral spacing of the right frame member 13 and the left frame member 15. The right frame member 13 and the left frame member 15 are chassis frame members, while the right frame member 82 and the left frame member 84 are body frame members. The right frame member 82 and the left frame member 84 can be continuous structural members that extend substantially an entire length of the body 14, or may be multiple discrete sections that extend along the entire length of the body 14. The right frame member 82 and the left frame member 84 can be configured to abut, rest upon, etc., the right frame member 13 and the left frame member 15, or may be configured to extend along lateral outer surfaces of the right frame member 13 and the left frame member 15, respectively, or may be configured to extend along lateral inwards surfaces of the right frame member 13 and the left frame member 15, respectively. In any of these configurations, the body 14 is fixedly coupled with the frame 12 through the frame members 82 and 84 and the frame members 13 and 15. The right frame member 82 and the left frame member 84 are rails, bars, beams, etc., and may have an I-shape, a rectangular shape, a T-shape, an L-shape, etc. The right frame member 82 and the left frame member 84 extend from an underside or bottom surface of the body 14, or may extend downwards from the floor surface 66 of the body 14 (e.g., the floor surface 66 of the refuse compartment 30).

As shown in FIG. 13A and described in greater detail above, the right frame member 13 and the left frame member 15 define the space 17 therebetween. The right frame member 82 and the left frame member 84 similarly define a space 74 therebetween. The batteries 100 can be positioned between the right frame member 13 and the left frame member 15, and also between the right frame member 82 and the left frame member 84. Specifically, the batteries 100 can be positioned within both the space 17 and the space 74. The batteries 100 can be fixedly coupled with the right frame member 82 and the left frame member 84 of the body 14 (e.g., fastened), fixedly coupled with the right frame member 13 and the left frame member 15 of the frame 12 (e.g., fastened), hung from underside of the body 14 (e.g., from the floor surface 66), and may extend into the space 74, or the space 17. For example, in some embodiments, the batteries 100 hang from the floor surface 66 and extend into the space 74 and/or the space 17.

Referring now to FIG. 13B, the batteries 100 can also be stacked relative to each other (e.g., in a vertical direction as shown) and positioned within the spaces 17 and 72. As shown in FIG. 13B, the batteries 100 can be positioned within both the spaces 17 and 72, with one of the batteries 100 positioned at least partially within the space 17, and another of the batteries 100 positioned at least partially within the space 74. In other embodiments, the batteries 100 are stacked relative to each other in a lateral direction between the right frame member 13 and the left frame member 15, between the right frame member 82 and the left frame member 84, or between both the right frame member 13 and the left frame member 15 and the right frame member 82 and the left frame member 84.

Referring to FIG. 13C, the batteries 100 are positioned within the space 74 between the right frame member 82 and the left frame member 84, but not within the space 17 between the right frame member 82 and the left frame member 84, according to another embodiment. In this embodiment, the batteries 100 are positioned proximate the underside of the body 14 (e.g., beneath the surface 66) but above the frame 12. Advantageously, positioning the batteries 100 as shown in FIG. 13C facilitates a tighter configuration with the batteries 100 shielded from debris or objects as the refuse vehicle 10 travels, due to the relative positioning between the batteries 100 and the underside of the body 14, between the longitudinal frames 82 and 84 of the body 14. The batteries 100 can be coupled with the body 14 by hanging from the underside of the body 14, fixed coupling with the batteries 100 and the right and left frame members 82 and 84, or both. The batteries 100 can be coupled with the right and left frame members 82 and 84 similarly as the batteries 100 are coupled with the right and left frame members 13 and 15 as described in greater detail above with reference to FIGS. 11C-11D.

Referring to FIG. 13D, the batteries 100 are positioned at least partially, or entirely, within a space 86 of the body 14, according to various exemplary embodiments. The space 86 is a tunnel, recessed area, or offset area relative to the floor surface 66 of the body 14. In this way, when the batteries 100 are positioned at least partially or entirely within the space 86, the batteries 100 extend upwards into the space 86 of the body 14 above the floor surface 66 of the body 14. In any of the configurations where the batteries 100 extend at least partially into the space 86, the batteries 100 may rest atop a top surface of the frame 12 (e.g., the right and left frame members 13 and 15), may be coupled with the right frame member 82 and the left frame member 84 of the body 14, and/or may be coupled with the right and left frame members 13 and 15. In any of the configurations where the batteries 100 extend at least partially into the space 86 of the body 14, the batteries 100 can extend between the right frame member 82 and the left frame member 84, or may extend between both (i) the right frame member 82 and the left frame member 84 of the body 14, and (ii) the right frame member 13 and the left frame member 15 of the frame 12.

The space 86 may be a tunnel or void that extends in the longitudinal direction along the body 14. The space 86 can also extend in the lateral direction along a width of the body 14. For example, the space 86 may extend in the lateral direction a distance that is substantially equal to a lateral spacing of the right frame member 82 and the left frame member 84 of the body 14, or a distance that is greater than a lateral spacing of the right frame member 82 and the left frame member 84. The space 86 can be an area that a prime mover (e.g., electric motor 18) and a transmission of the refuse vehicle 10 are positioned. The space 86 can also accommodate positioning of one or more of the batteries 100 as described herein.

Referring particularly to FIG. 13E, the batteries 100 are shown extending into the space 86 of the body 14, while occupying space between the first frame member 82 and the second frame member 84 of the body 14, but not occupying space between the first frame member 13 and the second frame member 15 of the frame 12. Particularly, the batteries 100 can be stacked or rest on top of the right frame member 13 and the left frame member 15 of the frame 12, and extend upwards, past the floor surface 66 of the body 14, into the space 86 of the body 14. In some embodiments, the batteries 100 are fixedly coupled (e.g., fastened) with the right frame member 82 and the left frame member 84 of the body 14, and extend upwards into the space 86 of the body 14. In some embodiments, the right frame member 82 and the left frame member 84 of the body 14 rest upon a top surface of the right frame member 13 and the left frame member 15 of the frame 12. The batteries 100 can be stacked on top of each other and at least partially extend into the space 86 of the body 14.

Referring particularly to FIG. 13F, the batteries 100 can be positioned to extend into the space 86, and to also extend into the space 17 between the first frame member 13 and the second frame member 15 of the frame 12. The batteries 100 can be fixedly coupled with the right frame member 13 and the left frame member 15 of the frame 12, and can be configured to extend through the space 74 defined between the right frame member 82 and the left frame member 84 of the body 14, and at least partially into the space 86. In some embodiments, the batteries 100 hang from an upper surface of the body 14 within the space 86 (e.g., the batteries 100 are hung from a surface 88 of the body 14) and extend into the space 86. The batteries 100, when hung from the surface 88 of the body 14 may also extend downwards, past the floor surface 66 into the space 74 between the right frame member 82 and the left frame member 84 of the body 14, and/or extend past the right frame member 82 and the left frame member 84 of the body 14, at least partially into the space 17 between the right frame member 13 and the left frame member 15 of the frame 12.

Advantageously, positioning the batteries 100 between the frame 12 and the body 14 (as shown in FIGS. 12A-12C) or between the right frame member 13 and the left frame member 15 (as shown in FIGS. 11A-11D) facilitates a robust and compact packaging and placement of the batteries 100. Further, positioning the batteries 100 as shown in FIG. 11A-11D or 12A-12C facilitates a lower center of gravity of the refuse vehicle 10, thereby reducing a likelihood of rollover and improving ride stability. In some embodiments, the batteries 100 are configured to store and provide electrical energy for usage on the refuse vehicle 10 (e.g., for use by the electric motor 18 to facilitate transportation of the refuse vehicle 10 or any other electric motor of the refuse vehicle 10). For example, the batteries 100 can be configured to provide electrical energy for one or more chassis operations or body operations (e.g., to operate a lift assembly of the refuse vehicle 10). In some embodiments, the batteries 100 facilitate a fully or semi electric refuse vehicle.
